HUMIDIFIER.

Application filed Februaryll, 1918. Serial No.

companying drawings, forming a part of this specification.

Our invention relates to a humidifier con" structed within either a steam or hot water radiator. The object of the invention is to provide wicks from which moisture supplied thereto will be evaporated by the air which is heated in the radiator itself. A further object of the invention is to provide means for applying moisture to the wick near the top thereof so that gravity will assist in carrying the moisture to the extremity of the wick. A further object of our invention is to provide a drip pan which is integral with the radiator and so positioned that if the radiator cools off while the moisture supplying means for the wick continues its operation the drip from the wick will be prevented from falling upon the floor and y will be later evaporated when heat is again applied to the radiator.

Our invention is illustrated in the accompanying drawings in which:

Figure 1- is an elevation, of a radiator containing a humidifier of our invention,

part or" the radiator being broken away;

Fig. 2 is a section on the line 22 of Fig. 1; and w Fig. 3 is a section on the line 33 of Fig. 1.

Similar characters of reference refer to similar parts throughout the severalviews. Our invention is an im' rovement upon the humidifier shown in our atent No. 1,249,432 and upomthe humidifier of our application Serial No. 203,490, filed February 23,1917.

Although not herein illustrated it is to be understood that the control apparatus illustrated in our said co-pending application may be used with the humidifier of our present invention.

The radiator to which our invention is applied is made up or". a plurality of. sec- Specification of Letters Patent.

tions 4, some of which may be of usual and unmodified construction while others of which, such as 5, 6, 7, and 8, are modified to form when the radiator sections are clamped together an upper tank or chamber 9 and a lower tank or chamber 10. The intermediate sections, such as 6 and 7, are provided with U shaped flanges 12 carried by the center columns 13 and adapted to be brought the corresponding flanges of adjacent radiator sections. The sections 5 and 8 are provided with flanges 14 for registration with the flanges 12 and also with inclosing end plates 15 which form when the sections are clamped together the ends of the upper chamber or'reservoir. The lower chamber or reservoir 10 is formed by registering flanges 16 on sections (5 and 7 and by flanges 17 a nd'end plates 18 on sections 5 and 8. Bythis construction the lower or drip reservoir is made about two inches Wider than the upper reservoir so that any water which overflows the upperreservoir-will be caught in the lower. A pair of Wicks 20 are hung over the side walls of the upper reservoir, the inner ends extending to a point near the base of the upper reservoir and the outer ends hanging a suitable distance over the sldes and between the middle and outer columns of the radiator.

.In .the operation of our invention Water is placed in the upper reservoir either automatically, as described in our co-pending application above referred to, or byhand. The portions of the wicks 2O hanging over the outside of the upper reservoir are kept wet from the water within the reservoir and since these wicks are suspendednear the top of the radiator they are pamed by a current of air which has already been heated.

from the lower portions of the radiator. By this arrangement a great deal more Water may be evaporated than would be possible with Wicks taking on their moisture at-the, bottom instead of at-the top. The wicks 20 may be made of suc length that in the or dinary operation of the device the water will beeva-porated at such a rate as to prevent dripping from the lower edge of thewick into the lower receptacle 10, but upon the cooling off of the radiator, as for example when the valve 22 is closed, the water continues to be absorbed by the Wicks 20 and accumulates at the lower edges thereof in such quantities that it drips into the lower receptacle 10. When the heat is again turned or the water which has accumulated in the lower receptacle evaporates, though provision may be made for drawing it off ii desired.

We have found linen cloth to be most satisfactory for use as wicks and have found it convenient to pass wires 23 through home in the cloth, though other obvious means may be used for retaining the inner ends of the wick beneath the liquid in the upper reservoir.

Having thus described our invention what we claim as new and desire to secure by Letters Patent of the United States is:

l. A combined radiator and humidifier comprising a plurality of vertically arranged radiator sect-ions, each section ineluding a plurality of spaced heating .conduits, cooperating flanges on certain of said sections forming upper-end lower water receiving reservoirs, and absorbent material for conducting water from the upper receptacle, a portion of said absorbent material extending over said lower receptacle, the lower reservoir being wider than the upper.

2. A combined radiator and humidifier comprising a plurality of vertically arranged radiator sections, each section including a plurality of spaced heating conduits, upper and lower base and side flanges forming part of certain of said sections and arranged to cooperate with similar upper and lower flanges of the adjacent section to form upper and lower watertight reservoirs wholly within the radiator, and absorbent material moistened by fluid from the upper reservoir and located over the lower reservoir.

A combined radiator and humidifier comprising a plurality of vertically arranged radiator sections, flanges on the sections uniting to form a humidifier chamber wholly within the radiator and located near the top thereof, absorbent material extending over the sideof said chamber and hanging downwardly between the heating conduits of said radiator sections, and a reservoir supported by said sections for receiving drip from said absorbent material.

4. A combined radiator and humidifier comprising a plurality of vertically arranged radiator sections, each section including three or more spaced heating conduits, a flange carried by an inner conduit and extending upwardly between the inner and the adjacent conduits, said flanges on adjacent sections uniting to form a water receiving chamber wholly within the radiator, a sheet of absorbent material having one end within the chamber and the other end hanging downwardly outside the chamber and between the heatin conduits of the radiator sections, and men s supported by said-sections for receiving drip from said absorbent material.

In witness whereof we hereunto subscribe our names this 6th day of February, 1918.
